Hello!

Thank you for posting. The interface ve command is not available because the switch appears to be running a switching image; therefore, this behavior is expected. If you need to configure an interface VE, you will need to run a routing image instead. Additionally, it seems the ICX is using a static IP. Could you please share the following information to help confirm?

#show version

#show run | inc dhcp

Thanks!
